The application is to be that January 10, application number in 2000 are 00804890.8 and denomination of invention dividing an application for the patent application of " supatex fabric and manufacture method thereof and equipment " applying date.

Technical field

Relate generally to non-woven fabric material of the present invention, make the method for this material and be used for making the various device of this material.

Background technology

As mentioned above, the present invention relates to non-woven fabric material, more specifically say, the non-woven fabric material that relates to has the outward appearance of Woven fabric and processes with the equipment of making this material and method easily, method is before the use adhesive is bonding, to stick with glue warp thread tension that agent slightly clings on the length on cylindrical bearing surface, use weft yarn along horizontal screw winding thereon then, the application of gluing agent is with the products with adhesive of finishing again.

The similar part of supatex fabric and Woven fabric and knit goods is that they all are the plane, flexible, as to be generally porous structures own, mainly by natural or synthetic fibrous material (yarn, line or filament).The unique distinction of supatex fabric be they can be processed must be similar to Woven fabric or knit goods, can also be made with than the physical property of weaving or knit goods is superior.Constitute the performance of fiber and the mode of manufacturing supatex fabric supatex fabric is had very big influence.The typical method of making supatex fabric is in the same place for fibrous material layer or network are interlinked with machinery, the chemical means with heat.

Summary of the invention

The present invention includes non-woven textile-like material." textile-like " material preferably has the particularly general appearance of Woven fabric of fabric, and the one or more features with traditional cloth fabric comprise quality evenly, compliance, intensity, appearance etc.An embodiment of textile-like material has many substantially parallel yarn fibers (or fiber substitute), and they are kept together by the combination at the yarn fibers bridge of a series of adhesive bridge of parallel fibers one side or adhesive and dispersion in the mode of not twisting.This textile-like material is made the back and just can be used, and the said other processing of perhaps available this paper further is transformed into other textile-like materials.The present invention also provides a kind of method and apparatus continuous, that form row to can be used to make this supatex fabric to make it have various required physical properties.Method and apparatus of the present invention is also made the supatex fabric can be to produce than the existing fast speed of Woven fabric system of making by further design.

" yarn " speech will be used in whole explanation, and this speech should broadly be interpreted as comprising monofilament and the multifilament yarn and/or the strand of various materials.The diameter or the DENIER of this yarn are changeable, and can make with multiple material, comprise following material but are not limited to these, as polyester, polyethylene, polypropylene and other polymer or plastics; Wool, cotton, hemp and other natural fabrics; The mixture of natural and/or synthetic fiber; And fiber substitute such as glass, metallic graphite carbon etc.It is contemplated that some warp thread and/or some weft yarn can be metal and/or alloy for example copper and/or aluminum steel, or the combination of metal and synthetic and/or natural fabric.It is also understood that the various density that will be referred to warp thread or weft yarn in the following description, this density is variable, depends on aforesaid yarn pattern and wants the desirable characteristics of manufactured nonwoven products.

For purpose of the present invention is described, " warp thread " material comprises the combination of any material or yarn, yarn or fiber alternative materials mainly are positioned on the mechanical bearing of trend of equipment and stretch at that time, and are aligned on this direction in check mode before forming the textile-like non-woven substrate sticking with glue material processed.And " weft yarn " material comprises the combination of any material or yarn, and the material that substitutes of yarn or fiber mainly is positioned in basically and extends on the vertical direction of yarn material at that time.

A supatex fabric that the spy is excellent of the present invention, its outward appearance be as Woven fabric, but be considered to supatex fabric, because warp thread and weft yarn do not interweave, just one deck is stacked in another above layer and glued together.This product of the present invention has several embodiment.First kind of embodiment comprises bonding machine comb net, wet-laying, airlaid web or spunbond net for weft yarn is laid on the substrate that is made of traditional supatex fabric.

In a more excellent non-woven embodiment, bonding machine comb net is used as the substrate of weft yarn.This net materials is specially adapted to of the present invention non-woven, because carding process is with regard to the character of itself, and typically can be on the operating direction of net with fiber alignment.The fiber alignments that most parts of fiber are extended on operating direction can cause a substrate wherein fiber imitating warp thread and directed vertical with weft yarn basically.When using up irradiation when watching according to product of the present invention, online machine comb fiber can cause the eye impressions of Woven fabric perpendicular to the orientation of yarn.

Bonding machine comb net can be sticked with glue the agent printing, perhaps according to one embodiment of the present of invention, can be before laying weft yarn the gluing lace or the lax window screening of random orientation be bonded on the surface of substrate lightly, this gluing lace can only lay than loose ground with adhesive weight seldom so that some weft yarn does not have and can be connected on the non-woven substrate of warp thread gluingly.This structure also has porous to a certain degree owing to have discontinuous adhesive and lay, can with have yarn and knit on yarn and do not have the gas permeability of Woven fabric of structure of film comparable.The structure that causes like this has improved feel and also can compare with weaving material.Adhesive also can use but other adhesive comprise the solid adhesive of hot setting adhesive and 100% preferably by thermoplastic polymer.The more excellent type formula of adhesive is preferably the copolyester of heat-activated, accounts for the 10-20% of the non-woven structure weight of finishing with regard to the weight speech.This gluing lax window screening cloth is clipped between the above-mentioned non-woven substrate and weft yarn by embedding.In case be activated, adhesive just can remain on weft yarn on the non-woven liner.

In also having an embodiment, many warp thread form a neat colony, parallel to each other basically and equidistant apart.If desired, can be with various warp thread for example warp thread of various types (synthetic, natural, yarn substitute) and/or yarn with various DENIER (fiber number), combine with this equipment, the non-woven fabric material that causes has interesting especially and particular performances.The equality colony of this yarn just is printed on adhesive coating one side of warp thread and fixes this colony on the throne effectively with the fuser roller applicator.The cooling of hot melt adhesive almost can be finished in moment, and the product that causes is a fixing guipure or a substrate, this substrate have basically the warp thread of many alignings and one basically just the position at the adhesive film of said yarn fibers one side.

A general herein excellent embodiment of spy through yarn material who uses is provided with a warp thread aligner, many independent yarns or line move through this aligner and just are placed on the up substantially flat aligned position, and in case be aligned, these yarns just move to the adhesive station, and this station is preferably a fuser roller (as the photogravure roller) applicator.In this device, the film of hot melt adhesive is printed on the just side of many aligning warp thread.Do not become a film and stay laying the back adhesive, in the time of on being applied to parallel yarn, adhesive can partly separate usually.The bridge of the short section of adhesive and/or yarn strand (being provided with or being provided with adhesive coating on each strand separately) forms at this point and/or not so extends across the gap between the parallel yarn.These bridges keep together each yarn and prevent that independent yarn or line from reversing mutually.

The employed noun of this paper " bridge " means adhesive film is applied to result actual on warp thread one side of aligning, it is the combination of the yarn strand section of knowing and/or the short section of yarn strand that (promptly on two or more points) contact with adhesive on the yarn of two or many alignings of gluing strand, adhesive applicating, a series of aligning warp thread are kept together by being spaced of selecting of user basically, and, can not reverse mutually between the yarn, rotate or separate owing to exist bridge in a side.In other words, these bridges lock yarn on the throne by warp thread material maker mode selected.Just can obtain one when adhesive cools off is easy to crooked but outward appearance unified standard, that have supatex fabric and the warp thread substrate guipure of feel.This warp thread substrate is suitable further to be processed into supatex fabric or to make his usefulness.If desired, the composition of this warp thread and adhesive can be wound onto reel so that with post processing, or is made into the purposes that thin slice is used for other needs.

More excellent warp thread aligner have a plurality of can the vertical direction displacement, isolated in the horizontal direction roller in groups.Above the position of one group of roller place horizontal plane be higher than the position of following one group of roller place horizontal plane.Certainly also can imagine, the orientation of roller not necessarily is divided into two groups up and down in groups, but about can being divided into two groups, perhaps be situated between upper and lower and about between orientation.Plane, roller place is with displacement in the horizontal direction rather than in the vertical direction displacement, perhaps at the direction top offset that is situated between between the two so in groups.These rollers transversely are aligned with each other roller.When these rollers are positioned in the horizontal plane, roller in each roller in one group is all organized with another departs from setting in the horizontal direction, between each roller in another group of each roller position in making one group, and the periphery of each roller in a group all covers on the periphery of each roller in another group.The warp thread that so transversely moves through roller in groups must move through above the group roller below last group of roller and down, contact with all rollers of each group, so has one section to engage arc with each roller.It is proper once to find to be about the 20 joint arcs of spending, and also can use but be higher or lower than these number of degrees.The outer surface of at least some rollers can make coarse, produces vibration in the plane of guipure so that be preferably on yarn.

Generally by being sent to above-mentioned these rollers after carding apparatus or the additive method coarse alignment, move through two groups of spaces between the roller as mentioned above from the warp thread that gets off through axle.These rollers are driven with the roll surface speed greater than the yarn linear speed.Once found to adopt this method that surpasses yarn linear speed driven roller can make yarn substantially parallel.Though the distortion roller turn round under the situation lower than yarn speed and also can reach identical effect, discovery once, it is highly effective making the roller overspeed operation in ratio is 2: 1 to 3: 1 scope.The parallel alignment of warp thread all is the part important affair concerning most of supatex fabric, because it can make yarn have uniform appearance, causes ultimate product to seem more as woven product.

The fuser roller applicator is a kind of more excellent fuser roller applicator.When this hot melt adhesive coating device of operation, the warp thread of series of parallel is pulled the gluing equipment that is supporting by by a series of rollers.The film guipure of hot melt adhesive (thick about 0.25 to 1 Mill) is coated over a side of aiming at warp thread as the intaglio plate shape continuously.The actual (real) thickness of film guipure can change within the limits prescribed, and depends on the weight of fabric, and the weight that is coated in the adhesive on the fabric usually is about 5% to 25% of fabric weight.For 50g/m ²Fabric weight, the adhesive of coating is about 2 to 15g/m ², preferably be about 5 to 10g/m ²After being capped as intaglio plate, the warp thread substrate solidifies rapidly, and being arranged in parallel of warp thread and equidistant apart are fixed up.The adhesive film guipure also can prevent reversing or rolling of warp thread, thereby keeps the feel of product.Be provided with cooling path, can guarantee that the adhesive guipure just hardened before substrate is drawn in, gathering for example can become web-like, plain film shape or other shapes and can decide with manufacturer or terminal use's needs.

The orientation of the yarn of Chan Shenging is that fiber is extended on operating direction in this embodiment, as the yarn in the fabric, the substrate of the non-woven fabric material that provides like this can be used in subsequently the non-woven manufacture process and makes non-woven fabric material, and this material can have such eye impressions of woven fabric material and actual feel.This material has the physical property above Woven fabric usually, and particularly relevant intensity, anti tear scratch etc. can not need with comprising that the post processing of chemical treatment reaches these performances.Post processing still can be used if desired, if when particularly can obtain useful performance thus.

Though above-mentioned bonding method is more excellent embodiment, other also can be used the method that the warp yarn strand of aiming at keeps together.Warp thread is contacted with an adhesive layer of doing, and heating its then, cooling makes material bonding; Adhesive can apply with the molten applicator that blows; Perhaps the warp yarn strand of Dui Zhuning can be adhered on another layer material by adhesive, on people's adhesive film or on substrate with adhesive and on another non-woven fabric material.

Another embodiment of supatex fabric of the present invention comprises the combination of warp thread and weft yarn, and weft yarn is positioned vertically with warp thread basically." perpendicular " speech is used to limit that the angle of intersection of weft yarn and warp thread is similar becomes 90 degree, and promptly intersecting with complete 90 degree has deviation, this deviation can reach about 5 degree on either direction, and the angle of intersection just may be spent from about 85 and change to about 95 and spend like this.Such product producing according to the present invention just has the angle of intersection that is about 89.7 degree.

In an embodiment of crisscross (or XD) equipment, warp thread and weft yarn are used to the bonding same a kind of adhesive material that becomes substrate of warp thread is bonded together.Concerning the single strand of 36 cotton yarns, thread density can highly arrive near 140 yarns/inches, and the density that this maximum that same cotton yarn and number had than conventional woven fabric is about 90 yarns/inches exceeds much significantly.

In the preferred embodiment of XD equipment, use the adhesive material (as lax window screening cloth, lace or analog) of open design can make the fabric construction of the completion of making have extremely good feel.This be since warp thread and weft yarn not by Chart-Park continuously to the position on have the ability that moves freely.This moment adhesive weight preferably less than the 5-20% of total weight.

Also having among the embodiment of XD equipment, the location of warp thread and weft yarn is orthogonal basically, and as mentioned above, but they are not lax window screening cloth or the lace bindings that sticks with glue, but link with the molten gluing guipure that blows.The molten method of blowing is that the industry is known and can cause the yarn of little DENIER.These yarns can lay more equably than gluing lax window screening cloth, but the adhesive that uses in structure is less.If little Denier yarns is suitably activated, the completion structure that causes can have good hand feeling, but than the completion structure that sticks with glue lax window screening and provide more uniform outward appearance is arranged.

Here the more excellent XD equipment that is used for linking through yarn material and weft material comprises following part:

(a) supply station is used for aiming at through yarn material and adhesive material, no matter be film, lax window screening cloth or lace; Or molten blow guipure or add other jointing materials in supply station to,

(b) one through the yarn material dispatching station, consistent with the outer surface of cylindrical bearing in the vertical so that along the longitudinal extension of supporting through yarn material there,

(c) weft yarn lays the station, moves through this station through yarn material;

(d) one is heated or adhesive activation station,

(e) cooling or adhesive sclerosis station and

(f) fabric is collected the station, as work beam, tablet press machine etc.

In the operation of a kind of XD of pattern equipment, be transferred to the supply station at the warp thread material transfer produced through yarn material manufacturing cell volume, on transition zone, move to from the supply station then and collect the station by this equipment.When yarn material moves through equipment, it is essentially cylindrical shape or cross section along one on transition zone can be the length of polygonal area supported and being supported, warp thread or warp fiber keep relation parallel to each other along columnar surface at that time, thereby are configured to be essentially the shape of cylinder through yarn material.There is a driven roller to be positioned to collect collecting between roller and cooling at its upstream or the adhesive sclerosis station of station.This driven roller rotates transition zone makes it move along the length of said area supported, advance and few tension force or do not have tension force during by equipment thereby make through yarn material, and speed is that be scheduled to and transformable.Perhaps, collecting roller can comprise that for example tablet press machine, laminating machine wait with other traditional process equipments and replace.

Before moving to adhesive activation station and sclerosis station, move through weft yarn through yarn material and lay many continuous weft yarns that stand over there and be wound onto around yarn material, adhesive material is set between yarn material and weft material at that time.Will be appreciated that when move through weft yarn through yarn material and lay when station, it still is essentially cylindrical shape.Cylindrical shape composite construction through yarn material, adhesive and weft yarn moves through activation station or heating station, and adhesive is activated there, will bond together through material and weft material not.Following closely, this conforms to structure and moves through sclerosis station or cooling stations, and adhesive is hardened there, so that is bonded in through yarn material and weft yarn and becomes a fixing basically supatex fabric together, but has the outward appearance of woven product.Those skilled in the art are when knowing, other can make the adhesive activation and eliminate the system that activates and also can use, and for example adopt system or other humidity control systems of moisture, high frequency light, pressure.There is a cutting knife longitudinally to cut, and when material continues by equipment,, can forces material to become flat shape because area supported changes pancake into from cylindrical shape gradually with conforming to structure.

In weft yarn lays the embodiment at station, be provided with the rotating cylinder of a sealing, have the inner chamber of a ring-type on a plurality of separately and independently reel, cone or analogs, to be loaded with the source of supply of a plurality of weft materials on it.This rotating cylinder has a columnar axial passage on its longitudinal axis, warp thread just moves through in this passage together with the adhesive that applies thereon.The weft material of each spool all is connected on the tensioning apparatus, and this tensioning apparatus also is installed on the rotating cylinder but just opens with cylindrical axial passage spaced slightly, therefore with comparatively approaching through yarn material and adhesive.Weft material moves through tensioning apparatus, subsequently around a guide pins, this guide pins also is installed on the rotating cylinder but with to the utmost for approaching through yarn material and adhesive coating, therefore when rotating cylinder during around its axis rotation, weft yarn just along horizontal wraparound around adhesive and warp thread.Tensioning apparatus can be conditioned, make when weft yarn is winding on yarn material, the tension force in weft yarn can be adjusted to warp thread in presumable tension force identical or bigger or less.

In the embodiment of above-mentioned tensioning apparatus, nearly the weft material of 12 reels can be installed on the radial wall in the rotating cylinder, for this reason even increase the size of rotating cylinder or increase the density of rotating cylinder inner reel.In rotating cylinder, provide the material of 12 spools can make tube obtain suitable balance at interval by predetermined equal circumference, so rotating cylinder not rotation at a high speed quiveringly basically.

In being arranged, the embodiment of tensioning apparatus also have main points to be, 12 reels or angular displacement such as use that any many reels must be done mutually exactly.Angular displacement accurately and weft yarn can make weft yarn accurately and controlledly place to the promotion of contiguous weft yarn, can optimize the coating of weft yarn like this.But, wait angular displacement just no longer to need so accurately if need the interval that alternately changes.The interval of fiber will be controlled by the angular spacing of predetermined yarn winding drum in this case.

In equipment, collect that the station is provided with that the energy makes transition zone and through yarn material advanced by equipment, rotating cylinder also had the other energy and can be used to make rotating cylinder to be different from the speed rotation of transition zone.Therefore, can move through equipment with selected fixed rate and/or variable bit rate straight line along its cylindrical bearing through yarn material, and rotating cylinder also can be with independent selected fixed rate and/or variable bit rate rotation.The weft yarn that will be wound onto like this on yarn material just can be reeled by predetermined, constant and/or required, variable interval, also can be by reeling with respect to the longitudinal axis mode at angle through yarn material.In other words, though weft material vertically is wound on yarn material basically, but be actually and depart from vertically slightly, and this deflecting angle is to change, as long as change the speed of rotation of rotating cylinder and the proportionate relationship of the linear speed that advances by rotating cylinder through yarn material.For example, if the user wishes to change the equispaced of weft yarn, need only regulate transition zone and get final product with respect to the speed of rotating cylinder.The difference degree that changes two speed just can change weft yarn interval on warp thread, also just changes be laid in angle on the warp thread of weft yarn by way of parenthesis.

In the excellent embodiment of a spy of XD equipment, there are the members of determining before several to be modified and/or to omit, this will discuss below in detail.Still continue to be supported on the transition zone and to become drum forms through yarn material.Driven roller still continues to drive columnarly makes it lay the station by weft yarn through yarn material, and the warp thread cylinder is supported so that lay weft yarn there.Heating station and cooling stations are used to make the adhesive sclerosis between warp thread and the weft yarn, and cylindrical shape is cut open and is flattened under tension force then, thereby makes the normal structure with Woven fabric outward appearance.

In this embodiment, weft yarn lays the rotating cylinder that the station has a sealing, is provided with ring-type inner chamber and a plurality of weft material on independent reel, cone or the analog that separates of a sealing in it.Rotating cylinder has a columnar axial passage on its longitudinal axis, warp thread and the adhesive that lays just move through this passage.Cylindrical axial passage is being equipped with a conical aligner, this aligner be used at last weft yarn with rotation direct into the vertical substantially position of warp thread on.The circular cone aligner is a fixing unit, and it has an angled or gradient surface to point to the direction of advance of warp thread.A more excellent gradient is considered to effectively from about 15 to 60 degree, and the gradient of 45 degree is best.

Each weft yarn all is sent on the fixing point of fixing circular cone aligner, glides along the slope of aligner then, and one is changed a ground and drops on the adhesive on the cylindrical shape warp thread exposed surface, and weft yarn just can not overlap each other like this.Under situation about closely coating, the tension force of giving weft yarn abuts against each other each weft yarn; And in the situation of loose coating, each weft yarn is not collided on the circular cone aligner usually, and when rotating cylinder rotated, they had a side of adhesive separately on the warp thread substrate along horizontal wraparound.As mentioned above, the rotating speed of rotating cylinder can change with the need, from extremely low (as 200rpm or still less) to very fast (as surpassing 1000rpm).The rotating speed of once finding to be about 500-600rpm when making more excellent supatex fabric is very useful.The tension force of weft yarn is the centrifugal force automated provisioning of being rotated generation by rotating cylinder at a high speed.

Will be appreciated that the tensioning of weft yarn and circular cone aligner weft yarn is directed into is placed on the surface of yarn material and the rotation of weft yarn loops pile warp yarn material can make the placement of weft yarn clock like precision.And the high accuracy that weft yarn is placed can cause high density that weft yarn coats and uniformity, and can according to known weft yarn laying method realize fabric structure, improve the overall efficiency of product.

Aforesaid stretcher embodiment, the weft material of a plurality of reels (as 8,10,12,14,16,18 etc.) can be contained on the radial wall in the rotating cylinder, for this reason in addition the density that will increase the size of rotating cylinder or increase the rotating cylinder inner drum enable to hold 12 reels up and down.The reel of even number is arranged in rotating cylinder easily equably.If but the reel of odd number suitably to arrange and keep the state of balance in rotating cylinder also be operable.

Though will be appreciated that as mentioned above nonwoven products can after-hardening draws the lamination of bright and clean and high-strength adhesive still keeping heating under the columnar state on the columnar area supported being essentially, also can use a kind of alternative heating and the method for after-hardening and lamination.

In a more excellent alternative method, it may be suitable that bonding warp thread and weft yarn are carried out the back lamination treatment.At this moment available laminating apparatus, or a unit that separates, or as an integral part of XD equipment, its position for example can and be collected between the roller at driven roller, and its form is preferably the flat rubber belting laminating machine.Nonwoven material by back lamination portion, is reheated and cooling again under predetermined tension, is wound on then and collects on the roller.Use flat rubber belting laminating machine can reduce curling of product and/or the contraction on cross section and obtain bonding preferably.

The excellent laminating apparatus of a kind of spy is the unit of opening in a minute, has one and is driven by dual band, and continuous shell of compression splenium utilizes pressure, heating and cooling that the adhesive that at least two substrates (sheet) are used between the substrate layer is bonded together.

This laminating apparatus that separates can be used to make multiple conform to and/or the material that strengthens.One or more parts in the lamination (being substrate or sheet) can be to weave composition material, supatex fabric guipure or fiber cushion.Adhesive material preferably thermoplastic is used to each substrate in the stromatolithic structure is bonded together.These adhesive materials can be melted and fusing more again and again.When being used for the particularly polymer yarn of lamination yarn, the most handy thermoplastic copolyester adhesive is because this material can the selected fusing point that makes its fusing point be lower than yarn.The industrial laminated fabric of available above-mentioned laminating machine manufacturing comprise with natural and/or synthetic fabric be base, that with asbestos be base, with the glass fibre be base, that with nylon be base, with flame retardant and/or antiblaze be base, and composition thereof.The laminated fabric of other materials also can prepare, and this is known to the those skilled in the art.

Supatex fabric with the XD device fabrication of top theory is that the excellent material of a kind of spy can be used as substrate or the sheet that uses in the said shell of compression press here.Best two supatex fabric all are the supatex fabric substrates, and one of them is equivalent to the weft yarn strand and another is equivalent to warp yarn strand.Being used for the adhesive that this two substrate is bonding should be able to be by thermal activation in lamination process.Make the adhesive activation with pressure and heat integration, still under pressure, make the substrate cooling of binding then, do to make final products reduce the size of contractions, the final nonwoven laminate fabric of setting to greatest extent and give product high strength to comprise the scratch-resistant performance like this.In addition, because this laminate product is made under pressure, warp thread is forced to closely contact with weft yarn, thereby is distributed on therebetween at the adhesive of interlayer, makes final laminate product have the outward appearance of woven product.It preferably occupies space between warp thread and the weft yarn in subtle mode to adhesive.

Being used for the laminating apparatus of optimum of pressure binding non-woven substrate has a shell or frame, and a rectangular forbay is housed on it.The shape of case not necessarily will be rectangle, but this shape is at present more excellent.Forbay has two isolated parts, i.e. a top and a bottom, and each part has wiper seal around it, and each part also all is provided with a plurality of heating element heaters and cooling element.Two rotating bands of rotation are in opposite directions arranged, promptly go up rotating band and a following rotating band for one, parallel to each other and together walk about by space in two parts of forbay.This two rotating band is the sealing big (length and width) of specific pressure case dimensionally, make this case on two bands and under supercharging, this is necessary.One band is driven by clockwise direction, and another band is by counterclockwise to being driven.In case rotating band action, an end of forbay just become import (input) end of laminating machine, the other end just becomes the port of export.

The bottom of more excellent forbay is contained on frame or the housing securely, and the top of forbay is owing to the needs that enter in the case can be conditioned.Under the normal condition, two parts by sufficiently spaced apart make two rotating bands can accompany betwixt or not accompany will by under the situation of the material of lamination, at (or under the state in pressure relief) under the pressure by the space between two parts.If desired, two positions also can be reversed, and top is fixed with the spring installation to make the bottom.

In lamination process, be moved through the wiper seal of forbay entrance point by the backing material of lamination, enter in two spaces between the rotating band.The air pressure that is applied to the forbay upper and lower presses to two air-locked bands together, causes a diaphragm effect at interband, thereby compression is located at the substrate of interband.Two bands can import backing material and thermoplastic adhesive by the motion of forbay continuously.In case enter, the diaphragm effect that substrate causes with regard to the pressure that is applied in is on tape pinched tight or is pressed together.The substrate of being pressed is heated under pressure then, causes adhesive fusing and distribution.Substrate layer is bonded together, and preferably the warp thread of at least some parts and weft yarn strand can occur at grade or near at grade.The substrate of heating still is cooled under pressure then, makes last laminate product.The laminate product of cooling leaves forbay by the outlet pressure sealing, is collected as required.When two or more non-woven polyester substrates (as at least one warp thread substrate and at least one weft yarn substrate) in this equipment during by lamination, the thickness of the laminated material of laminating machine outlet than measure in laminating machine import department substrate and the integrated thickness of adhesive to when young 5%, better to when young 10%, preferably at least about little by 20%.

The upper and lower of forbay is provided with a plurality of heating and cooling elements, is used for making thermoplastic adhesive's activation and sclerosis between substrate.Heating and cooling can be finished with the obtainable any means of expert.For example heat the hot rod of available heat ball, contact, hot rod, hot fluid (as oil), hot gas (as steam) and the analog of radiation.Equally, cool off available cooling fluid (as water), adiabatic cooling method, refrigerating gas and analog.If desired, available two pressure fluids that separate, one of them is used for heating, and another is used for cooling off.

In a special excellent embodiment, the position is installed securely at a plurality of hot rods and the cold bar of forbay bottom, and installed like this at a plurality of hot rods on forbay top and cold bar they can be floated on will be by the material top of lamination.Found once that such configuration was particularly useful to the preparation supatex fabric.Contraction can be reduced or eliminate, and last laminate product has the physical characteristic (feel and outward appearance) of a bright and clean fabric of crossing through overheated and machining.

Be preferably in the case of forbay entrance point,, preferably at least about have 25% at least about having 10%, preferably have 50% to be provided with hot rod approximately, and in the case of remainder at the port of export of forbay, at least about having 10%, preferably at least about have 25%, preferably have 50% to be provided with cold bar approximately.Because hot rod preferably is located at entrance point, cold bar preferably is located at the port of export.If desired, can comprise a plurality of thermals treatment zone and cooling zone in the forbay, as heating/cooling, heating/cooling, heating/cooling or the like.Perhaps, in order, can comprise a preheating section, heating and soaking zone and a cooling section.Unique requirement of successfully carrying out lamination is that the thermal activation and the hardening by cooling of adhesive all will be carried out under pressure.

The pressure area that popular rectangle forbay has is about 1500 square inches of (in ²).Basically by atresia The rotating band that coating covers is pressurized from the both sides of forbay, and used air (or other fluid media (medium)s) pressure is at least 2 pounds/side's inch (psi), preferably at least about is 5psi, preferably is at least about 10psi.Higher pressure can reach after revising in the supporting of equipment.This pressure that applies on tape is equivalent to be about 3000 pounds (1bs) are pressed in existing compression box to the weight that is about 150001bs (power) 1500in ²Area on.During lamination supatex fabric of the present invention, the compression stress from about 50001bs to about 150001bs is common, and the compression stress that is about 150001bs is considered to special excellent at present.This point is quite important, because in the shell of compression press of traditional use top board and base plate, if the weight of 150001bs is placed on when providing compression stress to carry out lamination on the top board, any band is not that to stop be exactly that fracture or both have when walking about under it, and this is because the excessive cause of friction that produces.The low pressure pantostrat press of this pattern (continuous, biobelt, heating/cooling zone) has for selling commercial.The compression stress maximum that this laminating machine provides is about 1/2pis, this upper limit generally will with the restriction that stops and rupturing.

The specific embodiment

The present invention includes three kinds of main supatex fabric manufacturing equipments, they can be separated to be used for producing the supatex fabric product and/or the use that preferably is combined, the feel of have high-quality as a means of producing, high strength and Woven fabric are such and the supatex fabric of outward appearance.The present invention generally comprises: (1) warp thread aligning equipment (two embodiment that the spy is excellent are arranged) and the supatex fabric product that produces therefrom; (2) the weft yarn laying apparatus (or XD equipment) (two embodiment that the spy is excellent are arranged) and the supatex fabric product of generation therefrom; And (3) high-pressure laminating equipment can be used to the product that XD equipment is produced is fused into anti-scratch, high-intensity supatex fabric.Some embodiment that describes in detail below has the member that increases and/or change, and these members can offer property the supatex fabric product of this equipment manufacturing.

A preferred embodiment of supatex fabric manufacturing equipment 60 is shown in Figure 1, this equipment has a frame 62 long and narrow, in line, comprise one through the yarn material supply station 64, weft yarn lays 66, heating stations in station 68, cooling stations 70, smooth station 72 that may comprise flat bed laminator 74 (Figure 1B) and one and collects station 76.As what will comparatively describe in detail later on, be located on a supply side reel 80 in yarn material supply station through yarn material 78.Preparing through yarn material manufacturing cell through yarn material, wherein two unit are with explanation in more detail below.

Warp thread substrate and manufacturing equipment thereof

A more excellent supatex fabric of the present invention has parallel yarn and remains on substantially parallel each other and state that do not reverse, and form is the non-woven sheets of a textile-like.This material is called as the warp thread substrate at this paper, once develops two manufacturing cells that form this substrate.In these two unit, adhesive all is the side of parallel yarn of being laid in.Adhesive can advantageously lay by pattern at random, forms the adhesive bridge between parallel yarn.These adhesive bridges can be the warp thread substrate spine are provided, and give the flexibility and the feel of its textile-like.These bridges also can make the fiber keeping parallelism and prevent reversing of single fiber.

In more excellent warp thread manufacturing cell 82 shown in Figure 42 to 51, this unit comprises that the warp thread 84 of supply moves through one and aims at station 86, enters into an adhesive and lay station 88, move to a driven transporting rolls 90 then, this transporting rolls 90 is used as the rewinding reel on warp thread equipment, as the loose winding reel, this will illustrate below on weft yarn (XD) equipment.Transporting rolls 90 also can be through the supply side reel in yarn material supply station 64 in the supatex fabric manufacturing equipment.Transporting rolls 90 can be taken on the warp thread supply station of supatex fabric manufacturing equipment shown in Figure 1, is guided the remainder of equipment there through yarn material.Certainly, manufacturing cell 82 and manufacturing cell 60 also can make an integral body, thereby can save transporting rolls 90 and will directly move in the supply station from manufacturing cell through yarn material 78.

The manufacturing cell of warp thread shown in Figure 42 to 51 82 comprises that a warp thread aligning station 86 and adhesive lay the frame 92 of station 88 usefulness.Adhesive is laid on the warp thread of aligning in adhesive lays the station, causes the lamination of warp thread and adhesive to be called as through yarn material 78.Will be appreciated that nonwoven products of the present invention has at least an embodiment not made by mutual incoherent warp thread, most main the substrate of interconnected fiber is made on warp thread or operating direction but just have by one.As bonding guipure through combing is this substrate with these features, but other substrates such as spunbond supatex fabric, the supatex fabric of airlaid web and the supatex fabric of wet-laying also all can use, but also is not limited to these.When use just contained the substrate of the warp thread that interconnects, this substrate just can move through through the warp thread of yarn material manufacturing cell and aim at station 86, laid station 88 but can directly deliver to adhesive.

Also comprise a yarn supply station 94 through yarn material manufacturing cell 82, this station keeping a plurality of levels of warp thread of coarse alignment and rotatable storage through axle 96, these warp thread at last by and be incorporated in yarn material.Will be appreciated that it is in order to reach required warp count through axle that a plurality of yarns are set, this density preferably is about 40 to 90 yarns of per inch.Each yarn axle is all rotatably located and is bearing on the frame 98 in the manufacturing cell, and by using traditional brake or friction retarding system 100 to come restraint of liberty to rotate, yarn can suitably be transported under tension force aim in the station.Yarn is stood by aiming at by driven transporting rolls 90 pullings.

Aim at that station 86 comprises two group 102 and 104 can be in the vertical direction displacement and in the horizontal direction apart from one another by the roller of opening 106.Above one group of roller 102 place horizontal plane be higher than following one group of roller, 104 place horizontal planes; Not necessarily to be divided into two groups up and down but can imagine these rollers, about also may being divided into two groups, or up and down and about between a certain direction grouping; Therefore roller not necessarily will be in the vertical direction displacement, and can be in the horizontal direction or other direction displacements.These rollers are aligned with each other in the horizontal.In addition, when these rollers are in horizontal plane, roller in roller in each group is all organized with another in the horizontal direction departs from (staggering), so that all the position is between the roller of another group for the roller in each group, and the outer peripheral face of roller can be overlapped on outer peripheral face of another group roller in vertical direction in one group.Like this, laterally moving through the warp thread of these two groups of rollers must be in the above under one group of roller 102 and pass through on one group of roller 104 of bottom right face, becomes one and is roughly sinusoidal or snakelike path as shown in figure 45.The camber lines that are approximately 20 degree of warp thread and each roller engage in more excellent embodiment, also can contact morely or less, and in a row roller from the roller to the roller, the contact amount can change.More excellent circle diameter is about 2 inches, but this diameter is not critical.In the embodiment shown, each group has 10 rollers, but also is not this number.If desired, these rollers can be heated and/or cool off, and this means can be used to give yarn required characteristic.

As can be seen from Figure 46, the outer surface of the roller 106 in the most close yarn supply station 94 cans be compared to the roller that lays station 88 near adhesive most and has thicker surface texturisation.The surface roughness that will be appreciated that roller is preferably laid the station from the supply station to the glue station to adhesive and is reduced gradually.To can be compared to the sand paper of 600 granularities most the thinnest for the surface texturisation of thick roller, more specifically says, estimates similar to the sand paper of 1000 granularities.The surface texturisation of utmost point warp is to use the material of those similar uses in traditional ceramic Analox roller to obtain, i.e. the LC-4 ceramic coating that is provided by the Praxair sufacing company of U.S. CT state New Haven.In at least one embodiment, be positioned at and aim at roller 106 that station 86 ports of export lay station 88 near adhesive and be actually polishing, therefore surface texturisation with dead smooth.

These rollers are driven by a drive system 108 they are rotated around separately longitudinal axis.The surface velocity of alignment roller 106 is obviously much bigger than the linear speed of warp thread when warp thread moves through the yarn alignment device.More excellent ratio is about 20: 1, and roller surfaces speed is about 300 to 500 inch per minutes, and the warp thread space rate is about 20 inch per minutes.Because it is so many that roller surfaces speed goes out the yarn linear speed greatly, why be appreciated that the warp rolls tube must be limited and do not allow it freely rotate in order to avoid yarn is overrun walks about.Other yarn/roller exposure level, roller speed, roller also can use speed ratio, roller surfaces quality and the surface texturisation variable gradient of yarn.These parameters are subjected to the yarn pattern to I haven't seen you for ages, the yarn group is thin and the influence of thread material.It is believed that the driving yarn of overrunning can discharge tension force and make Yarn relaxation and expansion, and the surface texturisation of roller 106 can make yarn vibration and swing, cause they and adjacent yarn to be collided, find one and the roughly equidistant stop place of adjacent yarn at last, this stop place is considered to the equilbrium position between the adjacent yarn.Why can aim in the yarn alignment device for yarn, this just conjecture at present, known to the people is that yarn can be aligned shown in Figure 46 to 49 really basically.

A more excellent system that is used for aiming at warp thread has been described above, and another system then is to use traditional carding machine to separate and aims at yarn.The system that is used for aiming at warp thread does not influence the aligning of weft yarn, but can influence the attractive in appearance of nonwoven products.After warp thread moved through warp thread aligning station 86, they were come adhesive and lay station 88.Adhesive lays the more excellent embodiment in station and has a gluing lax window screening or lace guipure supply side reel 110, and this reel has a traditional brake or a friction retarding system (not shown) can prevent from freely to rotate the running of consequently overrunning; Also have a gluing lax window screening or lace counterclockwise to rotation and driven carrying reel 112 and an infrared heater 114 contiguous with the carrying reel.Gluing guipure 116 moves under first dummy roll 118 (Figure 45 and 50) from its supply side reel 110, and upstream direction moves to the first half of gluing guipure carrying reel 112 then.On this carrying reel, gluing guipure moves through under infrared heater (can see best from Figure 45), is heated to adhesive there and begins to melt the temperature that is clamminess.Gluing guipure carrying reel this in inside by traditional mode with liquid coolant 120 coolings, therefore have only the outer surface of gluing guipure to be activated and be clamminess.In case be clamminess, gluing guipure 116 just in conjunction with or be incorporated in the warp thread 84, warp thread 84 is transported to the bottom of carrying reel downwards.Gluing guipure has enough structural integrities, can be as the carrier of yarn, in case thereon bonding, can make the yarn keeping parallelism and do not reverse.The warp thread that causes and the lamination of adhesive are embodiment through yarn material.So move the top cross second dummy roll 122 (Figure 45 and 50) through yarn material, be drawn to subsequently through yarn material collect or supply side reel 90 on gather there so that transfer on the supply station 60 of supatex fabric manufacturing equipment 60.Though it is to separate with equipment 60 of the present invention that warp thread manufacturing cell 82 once was illustrated, should know that this manufacturing cell can be combined into as a whole with other equipment through yarn material supply station 64 in the equipment.

More excellent gluing lax window screening or lace guipure are the hot melt adhesive of an energy heat-activated and hardening by cooling, and one of them example is made by the copolyester polymer of hot melt.The polyester guipure that a kind of such lax window screening or lace guipure are Bostic PE120-15, basis weight is every square metre 15 gram, it is that Bostic company by U.S. Massachusetts state Middleton produces.Warp thread for example is the polyester yarn of 36/1 spinning, can sell by the Burlington industrial group of U.S. North carolina state Greensboro or by the Carolina factory confession of same state Maiden.Above-mentioned warp thread 84 also can be used as weft yarn, and its mode will illustrate afterwards.Another kind of warp thread or weft yarn can be the polyester rovings of 30/1 spinning, can be supplied by the Uniblend spinning company of U.S. South Corolina state Conway to sell.Warp thread that other are available and weft yarn comprise commercial for sell with customizable fiber and analog.

Foregoing in the laminated construction of yarn material available non-woven substrate such as bonding guipure (not shown) through combing replace warp thread 84.A kind of such non-woven substrate is the Hollingsworth and Vose company manufacturing of U.S. Virginia state Floyd, and recognizes with model TR 2232.The basis weight of this supatex fabric should be every square metre of 40-60 gram, and the fiber denier number should preferably be about 1.5 between 1 to 5.

An excellent embodiment of spy through yarn material manufacturing cell of the present invention is shown in Figure 52 to 60.Figure 61 A is illustrated in the warp thread 84 of aligning and these yarns are kept together becomes detailed relation between the melt viscosity of the coacervation prod agent film 116B.Shown in Figure 52 to 60, warp thread manufacturing cell 82 comprises a yarn supply station 94, this station keeping a plurality of levels of warp thread of coarse alignment and rotatable storage through axle 96, these warp thread at last by and be incorporated in yarn material.Application knows that it is in order to reach required warp count through axle (be preferably in and have equal tension force in all yarns) that a plurality of yarns are set, and this density can be about 10 to 180 yarns from per inch, preferably is about 40 to 90 yarns of per inch.The thread density scope is comparable, and this is big or littler than this, depends on the characteristic that nonwoven material is required and the DENIER and the surface characteristic of used yarn.Each yarn axle is all rotatably located and is bearing on the frame 98 in the manufacturing cell, and by using traditional brake or friction retarding system 100 to come restraint of liberty to rotate, yarn can suitably be transported under tension force aim in the station.Yarn is stood by aiming at by driven transporting rolls 90 pullings.

Shown in Figure 55, aim at that station 86 comprises two group 102 and 104 can be in the vertical direction displacement and in the horizontal direction apart from one another by the roller of opening 106.Above one group of roller 102 place horizontal plane be higher than following one group of roller, 104 place horizontal planes; Not necessarily to be divided into two groups up and down but can imagine these rollers, about also may being divided into two groups, or up and down and about between a certain direction grouping; Therefore roller not necessarily will be in the vertical direction displacement, and can be in the horizontal direction or other direction displacements.These rollers are aimed in the horizontal mutually.In addition, when these rollers are in horizontal plane, roller in roller in each group is all organized with another in the horizontal direction departs from (staggering), so that all the position is between the roller of another group for the roller in each group, and the outer peripheral face of roller can be overlapped on outer peripheral face of another group roller in vertical direction in one group.Like this, laterally the warp thread by these two groups of rollers must be in the above under one group of roller 102 and pass through on one group of roller 104 below, becomes one and be roughly sinusoidal or snakelike path shown in Figure 55.The camber lines that are approximately 20 degree of warp thread and each roller engage in more excellent embodiment, also can contact morely or less, and in a row roller from the roller to the roller, the contact amount can change.More excellent roller diameter is about 2 inches, but this is not critical.In the embodiment shown, each group has 20 rollers, but also is not this number.

As we know from Figure 56, the outer surface of the roller 106 in the most close yarn supply station 94 cans be compared to the roller that lays station 88 near adhesive most and has thicker surface texturisation.The surface roughness that will be appreciated that roller is preferably laid gradually from the supply station to the adhesive and is reduced.To can be compared to the sand paper of 600 granularities most the thinnest for the surface texturisation of thick roller, more specifically says, estimates similar to the tissue paper of 1000 granularities.Superfine surface texturisation is to use the material of those similar uses in traditional ceramic Analox roller to obtain, i.e. the LC-4 ceramic coating that is provided by the Praxair sufacing company of U.S. CT state New Haven.In at least one embodiment, the position is actually polishing, the therefore surface texturisation with dead smooth aiming at roller 106 that station 86 ports of export lay station 88 near adhesive.As the foregoing description, if desired, these rollers can be heated and/or cool off, as a means of giving yarn with outstanding performance.

These rollers are driven by a drive system 108 they are rotated around separately longitudinal axis.Obviously the linear speed than warp thread is big for the surface velocity of alignment roller 106 when warp thread moves through the yarn alignment device.More excellent ratio is about 2: 1-3: 1, and roller surfaces speed is about 200 to 300 feet per minutes, and the warp thread linear speed is about 100 feet per minutes.Because it is so many that roller surfaces speed goes out the yarn linear speed greatly, why be appreciated that the warp rolls axle must be limited and do not allow it freely rotate in order to avoid yarn is overrun walks about.Other yarn/roller exposure level, roller speed, roller also can use speed ratio, roller surfaces quality and the surface texturisation variable gradient of yarn.These parameters are subjected to the influence of yarn pattern, thickness of yarn and thread material to I haven't seen you for ages.

It is believed that the driving yarn of overrunning can discharge tension force and make Yarn relaxation and expansion, and the surface texturisation of roller 106 can make yarn vibration and swing, cause they and adjacent yarn to be collided, find one and the roughly equidistant stop place of adjacent yarn at last, this stop place is considered to the equilbrium position between the adjacent yarn.Why can aim in the yarn alignment device for yarn, this just conjecture at present, known to the people is that yarn can be aligned shown in Figure 47 to 49 really basically.

Figure 60,61A and 61B illustrate one deck melt viscosity agent film best and are laid into a side of aiming at yarn subsequently, form the situation that the adjacent alignment yarn has the guipure that bridging connects.This film is cooled off by air, and the warp yarn fabric material of the cohesion that causes is collected for further using.Figure 61 A is for to be covered with the photograph that the adhesive bridge remains on fiber the parastate that does not reverse in warp yarn fabric one side.Figure 61 B is the photograph that parallel yarn does not have rubber cover stick one side, can determine that the warp thread substrate just is covered with adhesive in a side of fiber basically.Shown in this figure, though there is adhesive in a small amount to penetrate into opposite side by the warp thread substrate from a side that is covered with required bridge, all adhesive are retained in its coated that side on the aligning yarn basically.Can estimate in the adhesive that is laid, only to be no more than 10%, be preferably and be no more than 5% adhesive and leak into and aim at the untreated side of yarn.

Figure 57 to 60 illustrates more excellent adhesive applicating unit 88, and the warp thread 84 of Dui Zhuning moves through a series of rollers and contacts with hot melt adhesive application roll 90 with the one side there.This application roll 90 is driven through a groove that contains the hot melt adhesive 116A of fusing, so one deck strip of hot melt adhesive (about 0.25 to 1 mil thick) is printed to a side of aiming at warp thread as heliogravure.Figure 60 illustrates with an intaglio plate adhesive applicating roller 90 reduced form of adhesive applicating to aligning yarn one side.As shown in the figure, gravure roll is picked up the adhesive of fusing, adhesive just is laid in aims at a side of yarn, forms bridge thereon, in case the adhesive cooling, aiming at yarn just can become one flexible.

Figure 58 illustrates adhesive roller 90 that is coated with hot melt adhesive 116A film and the close-up view that is loaded with relation between the aligning yarn roller 122 of aiming at yarn 84.In this figure, this two roller is in the state that is disengaged, when they contacted with each other, the side that exposes of aiming at yarn 84 just was printed or applies last layer hot melt adhesive 116A film, aims at yarn and just become a flexible sheet 116B that solidifies when film cools off.

Shown in Figure 59, in order to guarantee that adhesive cools off fully or dry, can make aim at yarn solidify sheet and adhesive move through one in the station 95 a series of rollers and then to take-up ribbon spool 125.Locate non-woven warp yarn fabric material at this and be collected, so that further process or be used as supatex fabric.

More excellent adhesive is can heat-activated and the hot melt adhesive of hardening by cooling hot melt copolyester polymer for example, the EMS Grillon 1533 that the EMS chemical company of U.S. South Carolina state Sumter produces a kind of adhesive that comes to this.As for warp thread for example can be the polyester yarn of the Carolina factory of the Buclington industrial group of U.S. North Carolina state Greensboro or same state Maiden for 36/1 spinning of selling.The Uniblend spinning company that another kind of warp thread can be U.S. South Carolina state Conway is for the polyester roving of selling 30/1 spinning.

The alignment tab that the warp thread of aiming at is bonded together by the adhesive bridge in a side is an embodiment that the spy is excellent of the present invention.This supatex fabric has unique outward appearance, and as mentioned above, can make with the different yarns and/or the yarn substitute of any number, comprises metal such as copper, silver, Jin Bo etc.Aiming at outward appearance and the feel that the bridge that forms on yarn one side keeps together material and gives fabric.

This paper illustrates two embodiment of weft yarn equipment or XD equipment, and they all are to make weft yarn be substantially perpendicular to the warp thread of aligning.A kind of such equipment describes in detail in Fig. 1 to 7.Wherein through yarn material 78 one preferably by Be essentially columnar supporting structure 126 along one on the transition zone of making for no reason 124 and move, this supporting structure makes through yarn material roughly becomes cylindrical shape, and warp thread or yarn in the material are aimed in the vertical along being essentially columnar area supported.On cylindrical external surface, have just advancing of adhesive like this with predetermined speed through yarn material, lay when station when moving through weft yarn, with equidistant apart from one another by opening a series of weft yarns 128 of being disposed radially on rotating cylinder 130 (from Fig. 8,12-15,17 and 18 can see best) just with predetermined speed along horizontal wraparound columnar on yarn material.What cause like this is to advance by heating station 68 through yarn material 78, gluing lax window screening or being stacked on of lace 116 and weft yarn 128, and gluing there lax window screening or lace are activated, and will be bonded together through yarn material and weft material.Will be appreciated that and before weft yarn lays, adhesive to be sprayed on the warp thread as a kind of alternative method.And then make these materials move through cooling stations or adhesive sclerosis station 70, adhesive is hardened there, no longer is clamminess.Collect the station 76 the time when the fabric laminate 131 that causes advances to from cooling stations, have a cutting knife 132 to be preferably rotary cutter, longitudinally with cylindrical stacked incision, so laminated material is converted in the roughly one-tenth pancake that flattens station 72 from cylindrical shape gradually.In the downstream that flattens the station, transition zone moves down, and walks around the driven roller 133 (Fig. 2 B) below endless band, turns back to supply station 64 by idler roller 135 and dummy roll 137.

Laminated material also moves through a level bed laminater 74 in a preferred embodiment, after this it is wound onto one and batches on the reel 136 collecting the station, when needs or by preset time at interval, this reel can be taken away from equipment.Fig. 2 is for watching the schematic illustration of equipment among Fig. 1 downwards, and the material of warp thread shown in it is entering that weft yarn lays station 66 and the nonwoven laminate fabric product 131 that causes all is longitudinally or operating direction lay the station from weft yarn to collecting when move at station 76.Be clearly shown that supporting structure 126 in Fig. 4 to 7, it lays station 66 from the supply station by weft yarn and extends to and collect the station and be used for and will be bearing in required orientation so that process through yarn material 78 and last supatex fabric lamination 131.This supporting structure comprises that one 64 extends to and collects station 76 level through axle 138 from the supply station incessantly.This level is supporting rigid foamed material 140 or other suitable materials that covers thereon through axle, and this material can keep its shape muchly.Used foamed material is a kind of rigid polyurethane foams material, is made by Great Stuff, is sold to U.S. various places by Home Depot center, and this foamed material typically is used to make the window frame sealing.Can be clear that from Figure 4 and 5 that foamed material 140 with outside low friction shell 142 forms a straight upper surface in the supply station, and when foam material material when weft yarn lays station 66 extensions, shell is transformed into gradually and is essentially columnar shape.As seen from Figure 6, that is that how many shells of foamed material becomes semi-cylindrical shaped on supply station and weft yarn lay a centre position between the station; And when arriving weft yarn and lay the station as seen from Fig. 7, shell just is essentially cylindrical shape.Lay the driven roller 133 of standing from weft yarn, shell carries out opposite transformation again, and its purpose will illustrate afterwards.

By transporting rolls 90 supply that is located at the supply station, yarn material 78 in or fiber are by parallel and relation extension that keep to the side in the limit through yarn material 78.There are a suitable brake or friction system (not shown) to be used for preventing that reel 110 from freely rotating in order to avoid overrun and walk about.Material moves to be walked around a dummy roll 144 and is directed into for no reason circulation Be with on 124, this band supports through yarn material and it is advanced and lays the station by weft yarn. Band pastes on the stainless steel wearing plate that is incorporated in as foam material material 140 shells 142 with supporting structure 126 and slides.When beginning to be imported on the zone face through yarn material as shown in Figure 4, yarn in the material or fiber be by the parallel and relation kept to the side in limit location and along the longitudinal extension of equipment.Fig. 4 also illustrates gluing lax window screening or the lace layer 116 that is laid on yarn material.The material quilt The band supporting is also laid the station along supporting structure to weft yarn and is transported, and this moment, material had interior recessed arc downwards as shown in Figure 6 gradually.As shown in Figure 7, material just has cylindrical shape basically when laying the station near weft yarn, and a less axial clearance is just arranged in the bottom.

As shown in Figure 8, lay on the station 66 at weft yarn, the stainless steel nog plate of foam material material 140 and shell 142 all is interrupted just teflon band 124 continuation and lays the station by weft yarn and supported by a strong inner cylindrical ring 144 that extends along the total length of standing basically.Cylindrical shape ring 144 almost adjoins with foamed material 140, forms the continuation of laying the foam material material at station by weft yarn in fact.When

Band and be transferred through yarn material and only have a less clearance when laying the center at station by weft yarn.

Consult Fig. 8 and 17, weft yarn lay station 66 shell 146 have an antetheca or upstream wall 148 and center run through 150, one rear walls of circular hole or downstream wall 152 and aim at run through 156, one diapires 158 of 154, one roofs of circular hole and two sidewalls 160.As can seeing best from Fig. 8, another non-yielding prop ring 162 has a perimeter flange 164 usefulness bolts or additive method to be fixed on the rear wall 152 of housing at its upstream end and forms a cylindrical channel 166 that lays the station by weft yarn.Lay when station when conveyer belt extends through weft yarn, the inner cylindrical surface of support ring is spaced apart with conveyer belt on circumference.Support ring is carrying the inside race of the thin section ball bearing 168 of major diameter on vertical two spaced positions of its outer surface, the pattern that this ball bearing is provided as the Kaydon company of U.S. South Carolina state Sumter.The outer race of ball bearing is supporting another cylindrical body 170 of the inner cylindrical wall that forms rotating cylinder respectively.The inner cylindrical wall of rotating cylinder end bearing at its upstream preceding radial wall 172, supporting back radial wall 174 in its downstream, and these two radial walls is supporting the outer cylindrical wall 176 of rotating cylinder.Back radial wall 174 has concentric annulus and forms an inner ring plate 175 and an outer ring plate 177.Inner ring plate is fixed on the inner cylindrical wall 170 with securing member, and outer ring plate is fixed on the ring-type bead 179 with securing member, and this bead is fixed on the inner cylindrical wall 170, and this can see best from Figure 14.The variable-speed motor 178 that lays the station power facility as weft yarn is contained on the upstream face of housing antetheca 148, there is a driving shaft 180 to extend in the housing and supporting a driving pulley 182 and aiming at a ball bearing 168, and inner cylindrical wall 170 is supporting another belt wheel 186, rotating band 188 extends around this belt wheel, thereby operationally the driving pulley 182 with rotating cylinder and motor couples together, and rotating cylinder just can be by selected variable bit rate rotation when motor is switched on.The installation details of ball bearing and rotating band may be seen from the enlarged drawing of Figure 10 best.

The rear wall of rotating cylinder or downstream radial wall 174 have a plectane, have on it a plurality of (being six in an illustrated embodiment) along circumference apart from one another by the perforation circular hole of opening 190.Each circular all is provided with a circumferential seat 192, and therefore discoid closure plate 194 can be seated on the bearing, selectively circular hole is sealed.Discoid closure plate 194 can be fixed on the rear wall of rotating cylinder so that load onto and unload with refer to twisting screw fastener 196.This relation may be clearly shown that in Fig. 9,14,15 and 17.Each discoid closure plate 194 is all being fixed an eyelet in its geometric center, is positioned at the inboard of disk.This eyelet is as the guiding of weft material 128, and this will be explained below.The weft material that is provided with a plurality of forms and is reel 200 is for the source, and they can be contained on the inner surface of rotating cylinder antetheca 172 with taking away, be equally on circumference apart from one another by opening, and aim at circular hole 190 on the rotating cylinder rear wall.The number that will be appreciated that the weft material reel is transformable, though present embodiment is 6, also comparable these are many or few, in a more excellent embodiment, just once uses 12 such reels.Weft material extends on the relevant eyelet 198 of sealing disk 194 from reel 200, radially moves inward then by a gap 200 between sealing disk and rotating cylinder antetheca, and this can see from Figure 15 best.Related with each sealing disk what also aim at it diametrically is a stretcher 204, is used for controlling the tension force of the weft material that is contained in rear wall 174 downstreams.

Preferably consult Figure 14,18 and 31, stretcher 204 has the threaded bar 206 that stretches out to mechanical downstream direction, and this bar has plate-like bottom 208.There is a lasso 210 to be slidably disposed on the bar and also has bottom the plate-like of plate-like bottom 212 and bar 206 208 relative.Have a pagoda helical spring 214 to be contained in one heart on the bar, an end engages with lasso 210, and the other end engages with cap 216, and this nut can move and be positioned on any selected lengthwise position in rotation on the screw rod, thereby can change helical spring compression strength.Weft material 128 can slide between screw rod bottom and lasso bottom, but is subjected to the retardance of frictional force.The friction retardance that acts on the weft material can be regulated by the compression strength of spring.

Nestle up stretcher 174 and what aim at diametrically with the inner edge of rotating cylinder 136 rear walls 174 is a pilot pin, this pilot pin also stretches out to the downstream direction of machinery, and weft material extends around this pilot pin.Pilot pin also nestles up through yarn material 78, and the gap is about 0.15 inch, but other gaps also can be used.Thereby pilot pin can make weft yarn cross through yarn material exactly in 1,280 minutes to lay when rotating cylinder rotates in the following mode that also will be described in more detail.

May can see best from Figure 18, have a plurality of cross sections roughly to become L shaped horizontal adjustable plate 220 to be contained on the downstream surface of rotating cylinder rear wall 174, nestle up relevant stretcher 204 and pilot pin 218 and when upstream watching its location be right-hand formula clockwise direction at stretcher and pilot pin.Horizontal adjustable plate is installed like this makes it leave the thickness that is substantially equal to weft yarn 128 through the distance of yarn material 78 adhesive outer surfaces, thereby can guarantee that weft material evenly and flatly is wound on the gluing lax window screening or lace of yarn material.

Form is that a kind of alternative pilot pin of horizontal regulating block 222 is shown in Figure 30 to 36.This horizontal regulating block nestles up relevant stretcher 204, both can be used to guide weft yarn 128 and has been laid on yarn material 78, and the coiling that also can guarantee weft yarn can be arranged in individual layer on demand and be pressed together.Regulating block 222 can provide sizable control and yarn is accurately placed laying of weft material.Concerning 36/1 cotton yarn, weft yarn energy quilt very closely percent consolidation is that per inch is 140 or can be placed into an one thread exactly and be not more than ten thousand/several inches in abutting connection with yarn in locational difference.

Horizontal regulating block 222 can see from Figure 36 best that it is L shaped that its cross section roughly becomes, and an available pivot assemblies can be installed on the ring-type piece 224 on rotating cylinder 130 rear walls 174 inner rims (said inner ring plate 175 before replacing) rotatably around pivot.Pivot assemblies can see from Figure 30 and 31 best, and it comprises a chain dress and be fixed on pivot 226 on the horizontal regulating block with cap screw 228 that this pivot rotatably is contained on the interior a pair of ball bearing 230 of ring-type piece.Also have a cap screw 232 fixing within it at the inner terminal of pivot, this screw remains on a compression spring 234 between the butting surface 236 in end cap and the ring-type piece.The compression stress of compression spring can be regulated and be used for operationally spurring horizontal regulating block it is pressed on the packing ring 238 of a low frictional resistance with cap screw, thereby the flat regulating block of adjustable water saving is around the complexity of pivotal rotation.

Have a helical spring 240 to be anchored on the rear wall 174 and horizontal regulating block 222 of rotating cylinder 130, it can make the opposition end of regulating block flexibly be pressed on the weft material 128 below it, that reeled in the past.Can make weft yarn be wound into the level of a homogeneous like this, this is that the supatex fabric product finished is desired has, horizontal regulating block has two

legs

242 and 244, they form a groove in the junction, this groove can be controlled from relevant and adjacent stretcher 204 and transfer to the weft material line segment that weft material 78 lays the surface.Certainly, when the usage level regulating block, the horizontal adjustable plate 220 of explanation just no longer needed in the past.

An adjustable range regulator 248 is housed on horizontal regulating block 222, it act as the interval between horizontal regulating block of adjusting selectively and the ring-type piece 224 (Figure 30 and 31), groove 246 in horizontal regulating block can be aimed at stretcher 204, thereby weft yarn can move through the groove on stretcher and the horizontal regulating block along straight line before being applied on the gluing lax window screening.Adjustable range regulator 248 may preferably be seen from Figure 30,35 and 36, it comprises at the bottom of the L shaped wedge 250, there is a short-leg 252 to connect the circular channel 254 and a long leg 256 of same perforation on it, thereby has a groove 258 to make the long leg bifurcated form a pair of arm 2 that rides at the free end of long leg.Long leg is having gradient with to thicker and thinner on free end 260 at an end of contiguous short-leg 252 on the cross section.At the bottom of the L shaped wedge with one move through circular channel 254 in the short-leg, adjustable cap screw 264 is fixed on the end of horizontal regulating block 222, and galianconism is clamped between the retaining washer 268 on screw head 266 and the screw.Screw 270 interior also can the adjustings within it that the screw thread of screw is engaged with horizontal regulating block termination pass in and out screw in screw, just slide with respect to pivot 226 at the bottom of the L shaped like this wedge.Groove 258 in the long leg straddle make on the pivot a pair of ride arm 262 respectively on pivot and below.The slip of length between horizontal regulating block and ring-type piece along long leg 256 can make the spacing between the two be regulated at the bottom of the L shaped wedge when cap screw 264 passes in and out in screw.Preferably make with above-mentioned low friction washers 238 at the bottom of the L shaped wedge and dock by low-friction material, but make horizontal regulating block when needed free ring rotate around the ring-type piece.

Heating station or adhesive activation station 68 is made of cylinder formed core 272 steel or other heat transfers, this core position within conveyer belt 124 and then weft yarn lay the downstream at station 66 and form the rigid cylinder shape that weft yarn lays in the station and encircle 162 the portion that extends axially.Resistance heat element 274 also is connected on the power supply with electric wire 276 around steel core 272 along circumferential ring, this can see best from Fig. 8 and 10, electric wire extends through weft yarn and lays the interior cylindrical shape ring bearing in station, and be drawn out to outside the equipment by a circular hole 278 in it, it can be pegged graft in mode easily go up power supply.When leading to electric current on the resistive element, metal-cored 272 are heated, thus outside radiant heat, and this heat is by through yarn material and the gluing lax window screening or the cover layer of lace and weft material.That sends is hot controlled, and the adhesive activation in the gluing lax window screening is bonded together warp thread and weft yarn.Except said heating and cooling method here, the expert also can select other heating and cooling means for use, also can use as Steam Heating and water smoke cooling.

When the composite 131 of bonding warp thread and weft yarn was mobile downstream, what next run into was cooling stations or adhesive sclerosis station 70, this station comprises a steel equally or other heat conduction cylinder 280, and this position is below conveyer belt 124 tight.One heat transfer system 282 is arranged in cylinder, use coolant circulating, by input pipe and efferent duct 284 turnover, the heat of removing composite in a conventional manner.Cooling agent heat-transfer pipe as shown in figure 19 is connected on the heat transfer system, and cooling agent just can constantly circulate in cooling stations like this, makes the adhesive sclerosis of lax window screening or lace, thereby securely that warp thread and weft material is bonding.

When leaving cooling stations 70, continues when mobile downstream compound textile material 131, it is just run on the cutting knife 132 of fabric, this cutting knife is traditional style, being contained in one is right after on the support 286 under the foamed material supporting 140, when the composite 131 of warp thread and weft material during along the vertically moving of equipment, this cutting knife is used for along the length of composite it being cut.Heat or ultrasonic wave means (not shown) also can be used for making the cutting fusing of margin of textile material to open as being cut.

When the composite fabric material continued advanced downstream after incision, along with supporting structure 126 changes pancake in smooth station 72 into from cylindrical shape, the composite fabric material also was flattened.Therefore when non-woven fabric material arrival driven roller 133, move to then and collected the station at 76 o'clock, it is flattened on conveyer belt 124, at this moment just can be wound on and collect on the roller 136, till required textile material quantity is gathered.So this is collected roller and just can take away from machinery, change another and collect roller, said process can be gone ahead.

The supatex fabric that causes has warp thread and weft yarn is fixed together by adhesive, but adhesive only contact with the part of single yarn, and that is exactly just yarn and yarn or contacting of putting and put.In product, there is not an one thread to wish to be covered by adhesive fully.This factor can keep the feel of supatex fabric to make it more resemble Woven fabric.This supatex fabric is another special excellent embodiment of the present invention.

Further specify the manufacture method of a more excellent supatex fabric of the present invention and the operation of device therefor thereof below.Earlier will in yarn material manufacturing cell, prepare in yarn material supply side reel 90 installs to supply station 64, the pulling through yarn material make it be fixed to by equipment collect the station in collecting on the reel 136.Driven roller 133 is rotatably driven by a motor (not shown) with the speed identical with conveyer belt 124, motor is by a control system control in case 302 (Fig. 1-3), and this control system is also being controlled the motor that weft yarn lays station 66, heating station 68 and cooling stations 70.So can begin to make supatex fabric 131, warp thread be aligned adhesive coated thereon after, perhaps replacement scheme is to be used in the non-woven substrate of preparation in yarn material manufacturing cell 82 as when yarn material, drives driven roller 133 and conveyer belt 124 together with collecting reel 136.

With 124 supportings and make through the length of yarn material and move along equipment.On the supply side reel of yarn material, be added with a brake force (not shown) so that tension force and prevent from the overrun rotation of adjusting in yarn material.Next driving the rotating cylinder 130 that weft yarn lays in the station makes its clockwise direction rotation as Figure 17 and 18 situations of looking from the upstream.Warp thread advance and rotating cylinder rotation before, be contained in weft material strand in the rotating cylinder and connected by relevant eyelet 198, stretcher 204, walk around pilot pin 218 and initially snap on yarn material 78.Therefore when the rotating cylinder clockwise direction is rotated, each strand weft material is wound on yarn material just adjacent to each otherly, parallel at that time move through weft yarn through yarn material while straight line and lays the station.Will be appreciated that as long as change the rotating cylinder rotating speed and move through the ratio that weft yarn lays the linear speed at station through yarn material, just can regulate the spacing between the weft strands line, make each strand or closely adjoin or spaced slightly is opened, and this is accurate at interval but is variable, this depend on turn to and order about conveyer belt and through the yarn material straight ahead by the driven roller of rotating cylinder and the relative speed of conveyer belt.Certainly, big more through the linear speed of yarn material to the ratio of the speed of rotation of rotating cylinder, the weft strands coil of wire around the time spacing that forms also just big more.

It is also understood that owing to move at the operating direction straight line through yarn material, therefore when weft yarn is wound thereon, weft yarn can fully vertically not be wound on the warp thread or fiber in yarn material, even they are vertical basically.And when when the linear speed of yarn material increases the ratio of the speed of rotation of rotating cylinder, weft material can reduce with respect to the winding angle of warp thread or fibre length.In other words, when and when slowing down linear speed through wire material with respect to the speed of rotation of rotating cylinder, weft yarn can closely be wound on together and vertical with warp thread basically (promptly near 90 degree), but and during the speed of rotation of not corresponding increase rotating cylinder when increasing through the linear speed of yarn material, winding angle can descend, and for example drops to be about the 80-85 degree.Winding angle be machinery longitudinal axis and the parallel material webs around horizontal angulation.

As mentioned above, weft material be wound on gluing lax window screening and under it after around the warp thread of yarn material or the fiber, this composite moves through heating station 68, and adhesive is activated into the state of being clamminess and makes gluing or link together through yarn material and weft material there.When material continued to walk downstream, it moved through cooling stations 70, and adhesive is hardened there, and viscosity is removed, and became required supatex fabric but warp thread and weft yarn are bonding.Material continues when the length of machinery is advanced, the weft yarn of cylindric coiling is cut by cutting knife 132, thereby form the band of a non-woven fabric material 131, this band is moving towards driven roller or flat bed laminator 74 when (if you are using), is flattened along with the flattening of supporting structure 126 of this material of guiding.Come at last and collect on the reel (or tablet press machine, be not illustrated).This material is wound onto collects the collecting on the reel of station, and this reel can be taken away from this machinery when being gone up the non-woven fabric material of requirement by volume.

Gluing lax window screening or lace 116 through yarn material 78 can have various ways, but in a more excellent embodiment, it is a gluing strand, be fixed together randomly and have the guipure in gap between strand.The Bostic company of U.S. Massachusetts state Middlefon is shaped on suitable gluing guipure.When gluing alkene pine window screening when heating station is activated, adhesive does not cover the whole surface area of warp thread and weft material, but preferably lays a basis weight that is about structure gross weight 5-20%.The amount of the adhesive that lays has a direct impact pliability and the feel with the supatex fabric of above-mentioned device fabrication, certainly, this be one along with used lax window screening pattern and other adhesive materials and parameter that must control.

Adhesive material can with another kind of pattern be the molten adhesive that blows.Molten blow adhesive and have and can buy, perhaps available molten blowing on the adhesive supporting drum that applicator blows to adhesive the adhesive applicating device so that adhesive is stacked on the warp thread of aligning perhaps can be blown adhesive and directly blow on the warp thread melting.Molten advantage of blowing adhesive is the uniformity of guipure under the low-density situation of adhesive basis weight.Because melt blown fiber is little denier fiber, therefore can cause a low-density and very uniform guipure is used for warp thread is adhered on the weft yarn of supatex fabric.The uniformity of adhesive guipure can be improved the outward appearance of supatex fabric.

As mentioned above, change the rotating speed of rotating cylinder 130 with respect to the linear speed of conveyer belt 124, the coiling of weft material can be to be close to mutually or spaced apart.Both of these case is respectively shown in Figure 23 and 24.Warp thread all is close to mutually in this two figure, but the winding spacing difference of weft yarn 128.Figure 25 illustrates weft yarn 128 even bigger spacing can be arranged.But should know that even not obvious in the drawings, the winding spacing of weft yarn is big more, the winding angle that weft yarn is become with the warp thread longitudinal axis is just more little.In other words, along with weft yarn is more and more closely reeled, the winding angle of weft yarn rises near 90 degree, but when the spacing of weft yarn increased, winding angle just reduced, and for example is about the 80-85 degree.Figure 27 is that a diagram is illustrated in the gluing joint between warp thread 84 and the weft yarn 128, and the adhesive in Figure 28 to be a diagram be illustrated in lax window screening 116 just are laid in the labour of warp thread 84 on the surface of outermost.

Figure 29 illustrates can be with another embodiment that also has of the fabric of device fabrication of the present invention, and wherein weft material 128 is by making than warp thread 84 little DENIER or diameters.But should know that warp thread also can have the DENIER littler than weft yarn to make.For example the yarn of various types (synthetic, natural, yarn substitute) and/or the yarn of various DENIER all can be used as weft yarn to the mixture (not shown) of weft yarn when in addition, using this equipment.

Another more excellent pattern of XD equipment is shown in Figure 60 to 70, it have a frame 62 long and narrow, in a straight line ', comprise one through yarn material supply station 64 ', weft yarn lay station 66 ', heating station 68 ', cooling stations 70 ', smooth station 72 ' and one collect station 76 '.From collecting the complex nonwoven fabric of the present invention obtained at the station or can for example directly being used filter medium, perhaps can pressurized lamination become high-intensity, suitable composite fabric such as the canvas fabric that is used under the unusual condition as a lightweight.Shown in Figure 60 and 62, through yarn material 78 ' be located at through yarn material supply station 64 ' supply side reel 80 ' on.In case be placed on the supply station 64 of present device ' on, through a conveyer belt 124 for no reason, circulation of yarn material 78 ' just be moved to ' on, this is with the most handy PTFE Make.There are a series of bar and folding point (not shown) will be transformed into the curve form cylindrical shape through yarn material flat piece and conveyer belt.This folding carton equipment is road known in the art, in case when yarn material has the shape that is roughly cylinder and have adhesive layer to be laid on the outside or the surface of exposing, warp thread just can be wound thereon by weft material.

In case become cylindrical shape, through yarn material just can together with the adhesive film on its outer surface by predetermined speed advance by weft yarn lay station 66 '.When move through through yarn material weft yarn lay when station a series of be disposed radially rotating cylinder 130 ' on and on the rotating cylinder circumference with equidistant apart from one another by the weft yarn of opening just by set rate along horizontal wraparound columnar on yarn material, cause like this through yarn material 78 ', adhesive film 116 ' and weft yarn 128 ' composite construction just advance by heating station 68 ' adhesive is melted there, therefore warp thread and weft yarn are bonded together.

Following closely, this composite moves through cooling stations or adhesive sclerosis station 70 ' there adhesive and is hardened and no longer be clamminess.Bonding Fabric composites 131 ' from cooling stations to collect the station 76 ' advance, have this moment a cutting knife 132 ' be preferably rotary cutter longitudinally the cylindrical shape composite fabric to be cut, the composite fabric material of incision gradually from its cylindrical shape state be converted at smooth station 72 ' roughly become flat state.Downstream at smooth station, conveyer belt move down, walk around a conveyer belt of driven roller 133 ' there under endless band by idler roller 135 ' and dummy roll 137 ' turn back to supply station 64 '.Driven roller engages with the driving of endless band by it that just can making advances through yarn material passes through entire equipment like this.

Figure 63 is for watching the schematic illustration of equipment among Figure 62 downwards, and the material of warp thread shown in it lays station 66 ' and non-woven compound fabric product 131 of causing ' lay station 66 ' all be longitudinally or operating direction when collecting station 76 ' mobile from weft yarn entering weft yarn.

Through yarn material 78 ' by transporting rolls 90 supply that is located at the supply station, at the yarn of material 78 ' interior or fiber by parallel and relation that keep to the side in the limit is extended.There are a suitable brake or friction system (not shown) to be used for preventing reel 110 ' freely rotate in order to avoid overrun and walk about.Material moves walks around the PTFE that a dummy roll is directed into for no reason circulation

Be with on 124, this band supports through yarn material and it is advanced and lays the station by weft yarn.PTFE

Band is incorporated on the stainless steel wearing plate and slides with supporting structure 126 ' subsides.

Shown in Figure 63, weft yarn lay the station 66 ' on, PTFE (

With 124 ' continue to lay the station and by a strong inner cylindrical ring 144 that extends along the total length at station basically ' supporting by weft yarn.Weft yarn shown in Figure 64 lay station 66 ' a rear wall of shell 146 ' have or downstream wall 152 ' and aim at run through circular hole 154 ', roof 156 ', diapire 158 ' and two sidewall 160 ' (seeing Figure 65).Another non-yielding prop ring 162 ' have at its upstream end perimeter flange 164 ' with bolt or additive method be fixed on one of the rear wall 152 of housing ' go up and form by weft yarn lay the cylindrical channel 166 at station '.Lay when station when conveyer belt extends through weft yarn, the inner cylindrical surface of support ring is spaced apart with conveyer belt on circumference.Support ring on vertical two spaced positions of its outer surface, carrying the thin section ball bearing 168 of major diameter ' inside race, the pattern that this ball bearing is provided as the Kaydon company of U.S. South Carolina state Sumter.The outer race of ball bearing supporting respectively another cylindrical body 170 of the inner cylindrical wall that forms rotating cylinder '.The inner cylindrical wall of rotating cylinder radial wall 172 before end bearing at its upstream ', its downstream supporting radially disk 194 ', and these two radial walls supporting the outer cylindrical wall 176 of rotating cylinder '.Disk 194 ' be used for weft yarn is sent on the warp thread cylinder being provided with guide pillar 195 on its external margin radially.Radially the penetrale of disk terminates on the circular cone aligner 200, and this aligner has surface rounding, arc or the band gradient, can guide weft yarn and make it substantially vertically aim at warp.

As weft yarn lay variable-speed motor 178 ' the be contained in housing antetheca 148 of station power facility ' upstream face on.Have in a driving shaft 180 ' the extend to housing and supporting a driving pulley 182 ' with a ball bearing 168 ' aim at, and another belt wheel 186 of inner cylindrical wall 170 ' supporting ', rotating band 188 extends around this belt wheel, thereby operationally the driving pulley 182 with rotating cylinder and motor couples together, and rotating cylinder just can be by selected variable bit rate rotation when motor is switched on.The installation details of ball bearing and rotating band may be seen from the enlarged drawing of Figure 65 best.

Be provided with a plurality of forms and be reel 206 ' the weft material supply, they can be contained in with taking away rotating cylinder antetheca 172 ' inner surface on, be equally on circumference apart from one another by opening, and aim at circular hole 190 on the rotating cylinder rear wall '.The number that will be appreciated that the weft material reel is transformable, though present embodiment is 6, also comparable these are many or few, in a more excellent embodiment, just once uses 12 such reels.Weft material from reel 206 ' extend to disk 194 ' relevant eyelet 198 ' on, radially inwardly move downward through then disk 194 ' the surface come on another eyelet of disk 194 ' bottom.

When weft yarn lays when rotation station, weft yarn just by disk 194 ' on pilot pin provide out, so yarn slides on the slope of the band camber line of circular cone aligner 200, because this aligner, each weft yarn that is issued on the warp thread all can substantially perpendicularly be aimed at.Figure 69 and 70 illustrates circular cone aligner, particularly Figure 69 of the present invention best.Circular cone aligner 200 is a fixture, becomes a surface angle or gradient with direction of travel through yarn material.The rotation belt wheel that weft yarn is operated with rotating cylinder is issued on the surface of circular cone aligner.As the XD equipment that illustrated in the past, the mixture (not shown) of weft yarn, for example the yarn of yarn of various types (synthetic, natural, yarn substitute) and/or various DENIER all can be used as weft yarn and uses this equipment, and the supatex fabric that causes has prominent especially special performance.Single weft yarn respectively is be delivered on the lip-deep same substantially place of oblique wave of circular cone aligner, and they fall and be forced to one and be right after a ground and be arranged on the warp thread surface that adhesive covers from ramped surfaces.Figure 70 illustrate with the wide spacing of weft yarn the perspective view on yarn material of being laid in.Figure 69 and 70 illustrates the circular cone aligner from right side and left side respectively.In case weft yarn has been laid on yarn material, the adhesive between yarn must be heated and cool off and could form supatex fabric so.These steps will be carried out in next one of equipment.

Adhesive heating station 68 ' by cylinder formed core 272 steel or other heat transfers ' constitute, this core position conveyer belt 124 ' within and then weft yarn lay station 66 ' the downstream and form weft yarn and lay rigid cylinder shape in the station and encircle 162 ' the portion that extends axially.Resistance heat element 274 ' along circumferential ring is around steel core 272 ' and with electric wire 276 ' be connected on the power supply, this can see best from Figure 67 and 69, electric wire extend through weft yarn lay in the station the cylindrical shape ring bearing and by its a circular hole 278 ' be drawn out to outside the equipment, it can be pegged graft in mode easily goes up power supply.When leading to power supply on the resistive element, metal-cored 272 ' as to be heated, thereby outside radiant heat, this heat by through yarn material and on adhesive and the cover layer of weft material.That sends is hot controlled, enough melts adhesive warp thread and weft yarn are bonded together.

When the composite 131 of bonding warp thread and weft yarn ' mobile downstream, what next run into is cooling stations or adhesive sclerosis station 70, this station comprise equally a steel or other heat conduction cylinder 280 ', this position conveyer belt 124 ' perpendicular below.In cylinder, have a heat transfer system 282 ', use coolant circulating (as cold water) by input pipe and efferent duct 284 ' turnover, the heat of removing the composite fabric material in a conventional manner.Cooling agent heat-transfer pipe (not shown) is connected on the heat transfer system, and cooling agent just can constantly circulate in cooling stations like this, makes the adhesive sclerosis, thereby securely that warp thread and weft material is bonding.

Cooling stations 70 ' when continuation was mobile downstream, it was just run on the cutting knife 132 of fabric when compound textile material 131 ' leave, and this cutting knife is traditional style, be contained in support 286 ' on.When composite fabric material 131 ' along equipment length moves longitudinally the time, this cutting knife is used for along the length of composite it being cut.

When the composite fabric material continued advanced downstream after incision, along with supporting structure 126 ' transfer change in smooth station 72 ' interior pancake from cylindrical shape, the composite fabric material also was flattened.Therefore when non-woven fabric material arrive driven roller 133 ', move to then and collect 76 ' time of station, it conveyer belt 124 ' on be flattened, at this moment just can be wound on collect roller 136 ' on, till required textile material quantity is gathered.So this is collected roller and just can take away from machinery, change another and collect roller, said process can be gone ahead.If desired, compound warp thread and the weft material made at above-mentioned any XD equipment can be used as backing material again, further add man-hour and also need the weft material of adhesive material and interpolation, the composite construction that at this moment available following equipment is made.

The supatex fabric of shell of compression press and manufacturing thereof

If desired, the binding between warp thread and weft yarn also can be done more closely, for example uses laminating machine heating and cooling product under pressure.An embodiment of flat bed laminator is shown in Figure 1B, and it can be arranged on driven roller 133 and collect between the roller 136.It can adopt the conventional version of Britain Reliant manufacturing and is used for improving above-mentioned heating station 68 and cooling stations 70 respectively.Flat bed laminator can reheat under the state of setting level rather than under columnar state, cool off then supatex fabric make adhesive sclerosis, this point depend on the pattern of used yarn be sometimes effectively also can strengthen bonding.

The flat bed laminator of available the sort of pattern roughly illustrates in Figure 1B in equipment of the present invention.Will be appreciated that the set position of the laminating machine that is located at the device downstream end must can admit laminated fabric material of the present invention.Laminating machine comprises a housing 288, wherein be provided with a pair of driven press belt 290, the laminated fabric material is driven through a heating/cooling system 292 between this two band, first section of this system having the heater 294 formed by traditional heater coil or analog on the fabric second section be one on fabric, to have the cooler 296 of traditional cooling pipeline.Therefore reactivated or refuse under the state that adhesive was being set level before this when fabric moves through this system, sclerosis and then just is cooled.Press belt is applied to pressure on the laminated material from two sides up and down of laminated material when press belt 290 advances by heating/cooling system, therefore the cross section of laminated material is compressed, shown in Figure 40 for compressing preceding situation, wherein weft yarn just gently is bonded on the warp thread, and shown in Figure 41 for the compression after situation, wherein weft yarn further is embedded in the adhesive, therefore more closely is adhered on the warp thread.

After leaving cooler 296, the removable termination of walking around depression belt 290 of this fabric is upstream moved and is wound up into by a pair of dummy roll 300 then and collects on the roller 136.

The excellent high-pressure laminating equipment 400 of a kind of spy is shown in Figure 71 to 77.This laminating machine 400 has a housing or frame, and a forbay wherein is housed.This forbay has two isolated pressure portions, the upper and lower, and wherein the space that forms between two pressure portions is a lamination portion.Article two, counterrotating rotating band, last rotating band and following rotating band rotatably are contained in housing or the frame, and this two band contacts with each other and is installed in the driven roller pulling of the port of export and passes through lamination portion.There is a pressure generator to be used for air (or other fluid media (medium)-liquid or gas) pressure is fed in the upper and lower part of forbay as a means of being used for compressing the backing material of carrying under one's arms between two rotating bands.Pressure can be held, because this case all has wiper seal around being had a few of contacting with rotating band.In the rectangle case of present preferred embodiment, all be provided with sealing on the side of the upper and lower part of forbay, import and outlet also are provided with sealing, therefore can guarantee to produce in case required every effect.This equipment just can be to being clipped in the substrate pressurization between two bands when supplying pressure is arranged.

Consult Figure 71, wherein a plurality of main members that are used in the more excellent forbay 401 in the shell of compression press of the present invention are shown with section, comprise two belt bands, heading tape 402 and tail band 404, be contained in a plurality of backing rolls (top-410,420,430, bottom-510,520,530), respectively by separately driven roller 550 (top) and 650 (bottoms) pulling, and will be by the material of lamination between top 412 and bottom 414, enter, leave by forbay 401 and from the port of export 418 from entrance point 416.

Article two, belt aligning with 402 and 404 is kept by an electric alignment system, and this system has the slide 700 of aligning, aims at pivot 710, aims at electric servo 720 and aims at electric eye 730.If arbitrary band is not aimed at when mobile, electric eye 730 will detect and drive the aligning servo control mechanism, and this mechanism will make slide 700 carry out the position that band is adjusted in essential lateral movement.

Entrance point 416 at forbay 401 shown in the figure has 8 isolated radiation hot rods (320A, 320B, 320C, 320D......320H) and at the port of export 418 8 isolated cold bars (310A, 310B, 310C, 310D......310H) is arranged.4 hot rods (310A, 310C, 310E and 310G) are firmly mounted on the bottom 414 of forbay 401, and other 4 hot rods are then installed flexibly they are floated on heading tape, and the vicissitudinous material of thickness just can pass through under it like this.Cold bar also is that so 4 cold bars (320A, 320C, 320E and 320G) are firmly mounted on bottom 414, and other 4 cold bars are then installed neatly they can be floated on heading tape.

As illustrated, these hot rods and cold bar preferably are staggered, like this substrate below being heated Shi Xiancong, the back from top, again from following, or the like.Cooling also is like this, earlier from following, back from top, again from following, or the like.This arrangement can make and will be heated fast and equably under pressure and cool off by the backing material of lamination in the shell of compression press, the laminated material that causes causing has improved physical property, the supatex fabric that comes out of lamination like this, shrinkage factor is minimum and have the outward appearance and a feel of Woven fabric.

In more excellent embodiment, at least 75% bandwidth is by these element heating and cooling.For example, one 29 inches wide be with, 22 inches of central authorities are heated and cool off.One 76 inches wide be with, 60 inches of central authorities will be heated and cool off.Each bar of ER177A hot rod of Britain Reliant supply all be provided with thermocouple in case measuring radiation to on temperature, and each bar of cold bar all is provided with the cooling tube of transporting water.

The thickness of the glass fiber tape of PTFE dipping can be changed with the need, and depending on will be by the character of the material of lamination and the required operation rate in inch per minute (fpm).For the supatex fabric of lamination, tape thickness in the scope of 2 to 20 Mills, be preferably 5 to 15 Mills and once obtained gratifying effect.The band of 14 Mill thickness was once operated under 5fpm, and the temperature on the substrate is at that time The band of 5 Mill thickness was once operated under 12fpm, and the temperature on the substrate is 380 °F at that time.

Optimum belt speed

50,60,70...100fpm can change tape thickness and/or form and reach.Think that at present 60-70fpm carries out the optimum belt speed of supatex fabric lamination.The another kind of method that can reach higher rate is the size that increases laminating apparatus simply.The length of more excellent equipment is about 4 feet at present, size is increased to 2 to 10 times can uses speed faster.

In lamination process, backing material can produce counter-pressure owing to be trapped the expansion of air within it.In order to tackle this counter-pressure, the PTFE that in shell of compression press of the present invention, uses

Flooded at least one in the glass fibre rotating band (or two) and can do some modifications make it have the glass fibre surface layer of thick (about 0.125 an inch) porous on its outer ledge, the air that the surface layer of this porous can allow to expand is overflowed from the laminated material of heating by the hole of side direction (laterally).
